What is Debt-to-Income Ratio (DTI)?

The Debt-to-Income Ratio (DTI) is a financial metric that compares your monthly debt payments to your gross monthly income. Lenders use this ratio to assess your ability to repay loans.

The formula is simple: DTI=(Total Monthly Debt PaymentsGross Monthly Income)×100\text{DTI} = \left(\frac{\text{Total Monthly Debt Payments}}{\text{Gross Monthly Income}}\right) \times 100DTI=(Gross Monthly IncomeTotal Monthly Debt Payments​)×100

For example, if your monthly debts total $1,200 and your income is $4,000, your DTI is: 12004000×100=30%\frac{1200}{4000} \times 100 = 30\%40001200​×100=30%

Why is DTI Important?

Lenders rely heavily on your DTI to evaluate risk. A high DTI suggests that a significant portion of your income goes toward debt, making it harder to manage new loans. A low DTI indicates financial stability and increases your chances of loan approval.

Here’s how lenders generally view DTI ranges:

  • Below 20%: Excellent – Very low debt burden.
  • 20% – 35%: Good – Manageable and favorable for loan approval.
  • 36% – 49%: Fair – Could be acceptable but may limit options.
  • 50% and above: High Risk – Lenders may consider you overextended.
